Simulation of Hubbard model physics in WSe 2/WS 2 moiré superlattices
Yanhao Tang,Lizhong Li,Tingxin Li,Yang Xu,Song Liu,Katayun Barmak,Kenji Watanabe,Takashi Taniguchi,Allan H. MacDonald,Jie Shan,Kin Fai Mak +10 more
TL;DR: A new solid-state platform based on moiré superlattices that can be used to simulate problems in strong-correlation physics that are described by triangular-lattice Hubbard models is established.
Journal ArticleDOI
On the relationship of high coercivity and L10 ordered phase in CoPt and FePt thin films
TL;DR: In this paper, the microstructure and the room-temperature hysteretic magnetic properties of sputtered, 10 nm thin films of equiatomic binary alloys of CoPt and FePt were characterized using transmission electron microscopy (TEM) and a superconducting quantum interference device (SQUID) magnetometer.
Journal ArticleDOI
Advancements in the treatment and processing of electronic waste with sustainability: a review of metal extraction and recovery technologies
TL;DR: A review on the science and engineering of both conventional and innovative separation and recovery technologies for e-wastes with special attention being given to the overall sustainability is presented in this article, where physical separation processes, including disassembly, density separation, and magnetic separation, as well as thermal treatment of the polymeric component, such as pyrolysis, are discussed for the separation of metals and non-metals from ewaste.
Journal ArticleDOI
On the relationship of magnetocrystalline anisotropy and stoichiometry in epitaxial L10 CoPt (001) and FePt (001) thin films
Katayun Barmak,J. Kim,Laura H. Lewis,Kevin R. Coffey,Michael F. Toney,Andrew J. Kellock,Jan-Ulrich Thiele +6 more
TL;DR: In this article, two series of epitaxial CoPt and FePt films, with nominal thicknesses of 42 or 50 nm, were prepared by sputtering onto single-crystal MgO(001) substrates in order to investigate the chemical ordering and the resultant magnetic properties as a function of alloy composition.
Journal ArticleDOI
Deterministic coupling of site-controlled quantum emitters in monolayer WSe 2 to plasmonic nanocavities.
Yue Luo,Gabriella D. Shepard,Jenny Ardelean,Daniel Rhodes,Bumho Kim,Katayun Barmak,James Hone,Stefan Strauf +7 more
TL;DR: In this paper, the sharp corners of a metal nanocube are used to deform a 2D material to create an induced strain that can then create excitons at defined locations.
